Unlike Windows, there is no standard way to find out if java is installed on your machine unless ofcourse /usr/bin/java points to GNU java or the SUN java.
You can, at best, look into the environment variables LD_LIBRARY_PATH and PATH to see whether you have a JAVA related path in those env variables.

Hi,
I want to determine whether my java application is pointing to the OS version of Java or the User installed Java version on my Unix box.
I am aware of the "java -version" command, however I am unsure if the version returned is the OS one or the user one.
Please help.

git-check-attr
GIT-CHECK-ATTR(1) Git Manual GIT-CHECK-ATTR(1)
NAME
git-check-attr - Display gitattributes information
SYNOPSIS
git check-attr [-a | --all | attr...] [--] pathname...
git check-attr --stdin [-z] [-a | --all | attr...] < <list-of-paths>
DESCRIPTION
For every pathname, this command will list if each attribute is unspecified, set, or unset as a gitattribute on that pathname.
OPTIONS
-a, --all
List all attributes that are associated with the specified paths. If this option is used, then unspecified attributes will not be
included in the output.
--cached
Consider .gitattributes in the index only, ignoring the working tree.
--stdin
Read file names from stdin instead of from the command-line.
-z
Only meaningful with --stdin; paths are separated with a NUL character instead of a linefeed character.
--
Interpret all preceding arguments as attributes and all following arguments as path names.
If none of --stdin, --all, or -- is used, the first argument will be treated as an attribute and the rest of the arguments as pathnames.
OUTPUT
The output is of the form: <path> COLON SP <attribute> COLON SP <info> LF
<path> is the path of a file being queried, <attribute> is an attribute being queried and <info> can be either:
unspecified
when the attribute is not defined for the path.
unset
when the attribute is defined as false.
set
when the attribute is defined as true.
<value>
when a value has been assigned to the attribute.
EXAMPLES
In the examples, the following .gitattributes file is used:
*.java diff=java -crlf myAttr
NoMyAttr.java !myAttr
README caveat=unspecified
o Listing a single attribute:
$ git check-attr diff org/example/MyClass.java
org/example/MyClass.java: diff: java
o Listing multiple attributes for a file:
$ git check-attr crlf diff myAttr -- org/example/MyClass.java
org/example/MyClass.java: crlf: unset
org/example/MyClass.java: diff: java
org/example/MyClass.java: myAttr: set
o Listing all attributes for a file:
$ git check-attr --all -- org/example/MyClass.java
org/example/MyClass.java: diff: java
org/example/MyClass.java: myAttr: set
o Listing an attribute for multiple files:
$ git check-attr myAttr -- org/example/MyClass.java org/example/NoMyAttr.java
org/example/MyClass.java: myAttr: set
org/example/NoMyAttr.java: myAttr: unspecified
o Not all values are equally unambiguous:
$ git check-attr caveat README
README: caveat: unspecified
